Untrue.
Some have disputed this. But according to the book, "A concise history of the Christian church" by R. A Baker:
Irenaeus also quotes from, or alludes to, almost all the documents that become the orthodox NT. These citations are mostly from Pauline works (25+ occurrences from each of these: Romans, 1 Corinthians, Galatians and Ephesians). His Pauline citations/allusions include all three "Pastoral" epistles. The other general NT letters get scant recognition and a few are totally absent (Philemon, 2 Peter, 3 John, and Jude). He also refers to a few non-NT documents as “inspired” (1 Clement, Shepherd of Hermas).
By the time we come to the end of the second century and look at the citations of Clement of Alexandria(writings cir. 195-202) and Tertullian (writings cir. 205-225) we find hundreds of references from almost every NT document. The NT writings that are excluded by these two men are very similar to that of Irenaeus, but Clement then includes many writings as “scripture” that did not get final acceptance. One can take the citations from Clement and Tertullian and reconstruct the entire NT excluding the 4 or 5 small epistles which they neglect. Indeed, this is a very important factor from this point forward - “Did Clement/Tertullian cite from it?” These are the first two prolific Christian writers. From this point forward we find an increasing number of fathers writings great numbers of documents filled with biblical citations.
